Boob obsessed!!!!

So I am a mom to a 2-1/2 year old and she was never breastfed. She is constantly pointing out my boobs and how they are squishy. She even says she has boobs and tries to wear my bras or as she calls them “boob jammies”(I wear mine to sleep as well as during the day).

Is it normal for her to be sooooo fascinated by my boobs??? What can I do to get her to edge away? I know she will have questions and plenty of other things but I just figure it would be when she was a little older.
